it all depends on how the track prep is and the weather as well. for example, i went out a few months ago, it was about 70* outside, and the track prep was excellent, and was able to cut 1.9x 60 fts on 275-45-17 kumho's, leading to a 12.8 @ 108 with jsut a lid and open y-pipe (stock manifolds and y) slipping the clutch at about 3000-3500. but then i went out a couple weeks ago, after adding LT's and TD's, and it was about 80-85*, a lot more humid, and track prep wasn't up to par either, and the best 60 i could manage on the same tires was a 2.2x, leading to a 13.5 @ only 105 mph. it was a terrible night for street tire cars though, that pass i did beat a 01 zo6 (stock) and an earlier pass i raced a sbc s-10, and pulled on him, the driver said in better conditions it normally runs upper mid 12's as well

are you doing a burnout? I know EVERYONE says not to do a burnout on street tires, yeah will i followed that advice and got very similar times that you got. So the next time i went to the track i did a good burnout and got my best 60' of a 1.9. Im a six speed as well.

How long are you roasting the tires? First you should be able to drive around the water box and back up into it a little bit. For just street tires you just need to spin them for a few seconds to clean them off. If you do a smoke show all you do is make them slippery.

I say your 60ft times are average.. most stock 6speed cars wont run 1.9's or even 2.0's with a good driver.. your 60ft and trap is good enough to run you a 13.2 or lower.. i think your probably running the car to its potential, may try not running it as high into the rpms that usually helps me out a bit.. good luck man, better times will come with practice but i think your 60's are fine

stock tacs lag alittle bit i usually shift around 5600 unless im going 3rd to 4th that usually depends on how far i am from the finish sometimes i run it up a bit to keep from hitting 4th
